The Developmental Coordination Disorder Questionnaire (DCDQ) is a brief parent questionnaire designed to screen for coordination disorders in children, aged 5 to 15 years.
It was originally developed in the late 90's at the Alberta Children's Hospital, Calgary, Canada. Through further study with a population-based sample, a revision was developed, – sometimes referred to as the DCDQ'07 or as the DCD-Q.

A little bit about the DCDQ
The DCDQ is intended for use with 5 - 15 year old children. The questionnaire was studied with the parents of 287 children who were typically developing. Logistic regression modelling was used to generate separate cut-off scores for three age groups (overall sensitivity = 85%; overall specificity = 71%).
The DCDQ was then compared to other standardized measures in a sample of 232 clinically-referred children. Differences in scores on the DCDQ between children with and without coordination problems provide evidence of construct validity. Concurrent validity was evident with the MABC and with the VMI.
The DCDQ can be considered a valid clinical screening tool for children who have coordination challenges.
The Little Developmental Coordination Questionnaire is a parent report measure that screens for motor coordination difficulties in 3- and 4- year old children.
It consists of 15 items, which group into two distinct factors:
- Gross motor skills
- Fine motor skills
The Little DCDQ measures functional skills in several contextual areas across home and preschool environments and during play activities.
